Project description:Disease-specific induced pluripotent stem (iPS) cells have been used for a model to analyze pathogenesis of the disease. We generated iPS cells derived from a fibroblastic cell line of ataxia telangiectasia (AT-iPS cells). In analysis of AT-iPS cells, the human wild-type iPS cell line (MRC5-iPS) was generated and cultured in the same conditions as the diseased iPS cell lines. It is an ideal control cell line for the disease and patient-specific iPS cell lines. Because MRC5-iPS cells exhibited considerable chromosomal abnormalities in vitro, we performed a structural alteration analysis by using a SNP genotyping array for MRC5-iPS cell line, Tic, at passage 15, passage 30, and passage 37. The parental MRC-5 fibroblast cells and MRC-iPS 25 (Tic) were subjected to Illumina HumanCytoSNP-12 v2.1 BeadChip analysis.

Project description:By combining deep sequencing with high-throughput quantitative RT-PCR, we reveal that somatic splicing profiles are reorganized to pluripotent splicing profiles during reprogramming from mouse embryonic fibroblasts (MEFs) to induced pluripotent stem (iPS) cells. The splicing pattern in pluripotent stem cells resembles that in testis, and the regulatory regions have specific characters in length and sequence. These results indicate that the dynamic alteration in splicing is an integral part of the molecular network involved in the reprogramming process. Sequencing data from MEF, two iPS cell lines and one ES cell line. RT-PCR data will be represented within Figures or Tables in published manuscripts.

Project description:Human induced pluripotent stem (iPS) cells have previously been derived from somatic cells using viral vectors that integrate transgenes into the genome. Genomic integration, however, can allow persistent leaky expression of the transgenes and can create insertional mutations, thus limiting the utility of these cells for both research and clinical applications. Here, we describe the derivation of human iPS cells free of vector and transgene sequences using non-integrating oriP/EBNA1-based episomal vectors. The resulting iPS cells are similar to human embryonic stem (ES) cells in both proliferative and developmental potential. These results demonstrate that reprogramming of human somatic cells does not require genomic integration or the continued presence of exogenous reprogramming factors, and removes one important obstacle to the clinical applications of these cells. This SuperSeries is composed of the following subset Series:; GSE15175: Human induced pluripotent stem cells free of exogenous DNA are derived with episomal vectors (fig 1.c); GSE15176: Human induced pluripotent stem cells free of exogenous DNA are derived with episomal vectors (fig 4.a) Experiment Overall Design: Total 21 samples were analyzed to confirm the similarity of human iPS cells derived with episomal vectors with human ES cells, and a dissimilarity with fibroblasts. Experiment Overall Design: Refer to individual Series

Project description:We performed single-cell sequencing to characterize the cell types that are present in human induced pluripotent stem cell derived (iPS) kidney organoids and their transcriptional profile. Furthermore, using bulk RNA sequencing we compared the transcriptional profile of kidney organoid derived podocytes from a wildtype iPS line, an iPS line with 2 mutations in podocin (NPHS2) which causes clinical manifestation of nephrotic syndrome and an iPS line with one of these mutations repaired which causes no clinical symptoms. For reference and comparison we took along human in vivo glomeruli and a human conditionally immortalized podocyte cell line.

Project description:Pluripotency, the capacity of embryo-derived stem cells to generate all tissues in the organism, can be induced in somatic cells by nuclear transfer into oocyte, fusion with embryonic stem cells, and for male germ cells by cell culture alone. Recently, murine fibroblasts have been reprogrammed directly to pluripotency by ectopic expression of four transcription factors (Oct4, Sox2, Klf4, and Myc) to yield induced Pluripotent Stem (iPS) cells. Using the same four factors, we have derived iPS cells from human embryonic stem cell-derived fibroblasts, primary human fetal cells, and diverse cells of neonatal and adult human origin. The human iPS cells manifest the colony morphology, gene expression patterns, and epigenetic characteristics of human Embryonic Stem (hES) cells, and form well-differentiated teratomas in immune-deficient mice. These data demonstrate that defined factors can reprogram human cells to pluripotency, and establish a method whereby patient-specific cells might be established in culture.

Gene expression of those cells were analyzed.

Project description:Reprogrammed somatic cells offer a valuable source of pluripotent cells that have the potential to differentiate into many cells types and provide a new tool for regenerative medicine. In the present study we differentiated induced pluripotent stem cells (iPS cells) into hepatic cells. We first showed that mouse iPS cells could from a complete liver in mouse embryo (E14.5) including hepatocytes, endothelial cells, sinusoidal cells and resident macrophages. We then designed a highly efficient hepatocyte differentiation protocol using defined factors on human embryonic stem cells (ES cells). This protocol was found to generate more than 80% albumin expressing cells that show hepatic functions and express most of liver genes as shown by microarray analyses. Similar results were obtained when human iPS cells were induced to differentiate following the same procedure. Experiment Overall Design: Total RNA was harvested from the following sources and used for Affymetrix array analysis following manufacturer defined protocols: Experiment Overall Design: 1) human foreskin fibroblasts, ATCC cell line CRL2097, 3 independent cultures Experiment Overall Design: 2) induced pluripotent stem (iPS) cells derived from CRL2097, 3 independent undifferentiated cultures Experiment Overall Design: 3) induced pluripotent stem (iPS) cells derived from CRL2097, 3 independent cultures harvested at day 20 (d20) of a hepatic differentiation protocol Experiment Overall Design: 4) WAO9 human embryonic stem cells, 3 independent undifferentiated cultures Experiment Overall Design: 5) WAO9 human embryonic stem cells, 3 independent cultures harvested at day 20 (d20) of a hepatic differentiation protocol. <br><br>This experiment was reloaded in November 2010 after additional curation

Project description:In this study, we explored x-inactivation in monkey embryos (ICM and TE separately) and pluripotent stem cells (IVF derived ES, SCNT-derived ES and monkey iPS) To elucidate x-inactivation in experimentally reprogrammed pluripotent cells, we derived pluripotent stem cells by both SCNT and iPS approaches from same parental skin fibroblasts. We also compared gene patterns of those cells to IVF-derived counterpart. The transcriptomes of rhesus monkey embryonic stem cell lines derived by both SCNT (CRES) and iPS (RiPS) from same monkey skin fibroblasts were compared each other. Both experimentally reprogrammed cells were also compared with IVF-derived counterpart (ORMES23). Finally, the adult somatic skin fibroblasts were analyzed. Three biological replicates of each cell line (A, B, C) were analyzed.
